Hi, I was just wondering how would high levels of Glutathione boost our immunity against SARS. Also, if high levels of Glutathione are all we need to prevent getting SARS, then don't we hear it in the news? This leads me to think that maybe it is not so simple that a mere increase in Glutathione levels will help us prevent SARS. After all, if our biochemistry were not so complex, a panacea would have came out long time ago, wouldn't it?
